The new corrugated separators are made with the same
raw material and extrusion process as the standard Amersil
ribbed product. Their composition is limited to two basic
materials, precipitated silica and pure polymer. There is no
additive, mineral oil nor resin, therefore, the final product
has very high chemical purity. The chemical resistance of
the separator is also improved by the fact that the mixture of
silica and polymer is not extruded by heat, but at ambient
